Referring rst to Figs. l andv 2. at 30 we have shown. one of the front doorsY of. an enclosed f automobile,v the door being provided, with a conventional glass panel 31 adapted. to. be dropped into and lbe raised from the. door compartment 32.. At 33-33 are. shown the, sillV elements between which the panel3l is adapted to bev raised and lowered in any suitable or well known manner.

The embodiment of our invention illustra-ted,

in. Figs. 1 to 10 inclusive comprises the tray proper 34, preferably formed of metal, to the bottom of which is spot welded a pair cf, transverse metal straps 35-35 having upturned ends 36-36 which lie adjacent the same, longitudinal edge of the tray. The angularityy of tl e upturned ends 36-36 with respect to the straps by which they are carried, preferably is slightly acute. Encircling each strap 35 atv or adjacent its upper end is a suitable cushioning sleeve 37, which preferably is formed of soit rubber.

Each of the upturned strap ends 36 is apertured at 38 and is provided with end edge and side edge notches, 39 and 40 respectively, which, in their relation to the axis of aperture 38, are located ninety degrees apart. Located in each of the apertures 38 is a loose sleeve 4l which lies around the threaded portion of a screw 42, a washer 43 preferably being inserted between each sleeve 41 and the head of; its associated screw 42.

The threaded extremity of each screw 4,2 preferably is threaded and riveted into the end of one of a pair of tray supporting arms 44.-44, these tray supporting arms preferably being formed of scrap steel stock having substantial rigidity and having unpivoted ends of tapering cross section as indicated at 45p-45 in Fig. 8..

Each of the tray supporting arms 44V is provided at its upper or pivoted end with a lug 46, which conveniently is pressed from the metal of the arm, such lug preferably being substantially V shaped in cross section, as viewed in both Figs. 5 and 7.

The lug 46 of each of the tray supporting arms 44 is adapted to engage in the notches 39 and 40 of its associated upturned strap portion 36e-i. e. adapted to engage in the notch 39 when the arm depends from the tray, as shown bythe full lines in Fig. 6, and adapted to engage'v in notch 40 when the arm occupies the raised or broken line position of the same figure.

At 47 is shown a locking and adjusting device, common to both of the tray supporting arms 44.-44, such adjusting device consistingofA an elongated metal strap member provided nearA its ends with elongated slots 48-48j, Whichslidingly receive the sleeves 41-41 to which wev previously have alluded. The metal at the upper. and lower edges of each of the slots 48 is turned laterally and conformed to constitute wedges or straight faced cams 494-49 which cooperate with the washers 43 of the screws 42. The wedges or cams 49-49 terminate short of the ends of their associated slots 48. All of the wedges or cams taper in the same direction (i. e from right to left as viewed in Figs. 3, 6 and 7). The bar .47 is provided with offset ends 50-50 to facilitate its lateral shift with respect to the tray.

When the tray is not mounted on a vehicle door or other suitable support, the arms 44 mayoccupy the horizontal or dotted line positions of Fig. 6.

In this horizontal position the arms are above the tray bottom,- or in other Words, they' are' witl'iirr4 the receptive depth of the tray. When the arms 44 occupy these upper or horizontal positions their lugs 46 engage in the notches 40 of the upturned ends 36 of straps 35, and are tightly held in such notches due to the cooperation ot the wedging cams 49 with the washers 43 of screws 42. When the supporting arms areV to be locked in their upper or horizontal. positions, the bar 47 is shifted slightly to. the left from the position shown in Fig.A 6..

Let us: assume that the tray 3,4 is loaded and is to be mounted upon. the car door, either interiorly, as indicated by full lines in Fig. 1, or exteriorly, as indicated by the dotted lines in the same figure. The waiter, with a finger of one of the hands with which he is supporting the tray, shifts the4 bar 47 to the right (Figs. 6 and 7) to permit the lugs 46-46 of the supporting arms to become unlocked from the notches 40--40, which such lugs occupy when the supporting arms are in their elevated or horizontal positions. When this occurs, the supporting arms drop by gravity to the vertical positions illustrated in the drawings. The supporting arms 44-44 are then inserted into the glass panel slot of the door, as shown in Figs. 1 and 2, with the rubber cushions 3.7.-37 resting upon one of the sills 33, and with the lower ends of the supporting arms bearing against the glass panel 3,1. Usually, when the supporting arms are thus inserted into the door slot, it will be found that the supporting surface of the tray does not occupy a true horizontal plane.v In most. instances, due tothe clearance between the glass panel 3l, and the sill whereon the cushions 37 rest, and/ or the lateral curvature of a road whereon the, vehicle is standing, the tray Will incline downwardly away from the door. To cause J611e supporting surface of the tray to assume a truly horizontal position, the bar 47 is then pressed to the left (Figs. l, 6 and 7). When this occurs, the camming wedges 49 cooperate with the Washers 43 of screws 42 to draw the tops of the upturned ends 36 of straps 35 toward the upper extremities oi the supporting arms 44. When this; Occurs, the lower portions of the upturned ends 35, having the contiguous portions of the Supporting arms 4.4 as. their fulcrums, turn in the, clockwise direction (Eig. 8), this movement being continued until the supporting surface of the tray assumes al truly horizontalv plane. Under these conditions, the lugs 46-46' at the upper ends of the supporting arms 44 are engagingthe notches 559-39, at the tops of; the. up turned ends 36; Qf; thel tray carrying straps 35. Since the. adjusting barA 47 is common: to both of the supporting arms 44, it will be understood that the angularityof the two supporting arms 44, with respect to the supporting surface of the tray; may be effected simultaneously and to precisely the saine extent. This adjustment of the supporting arms to place the', supporting surface of the tray in the true` horizontal position, i's very' readily and easily accomplished by slight pres-- sure of one finger-upon the right hand end' (Fig. 7) of the adjusting bar 47.

thus permitting the disengagement of the arm lugs 45 from the notches 39 of the upturned ends: Both arms then may be swung to of straps 35. their horizontal positions and there locked by a'- left hand movement (Fig. 6. ofbar 47). This lastl mentioned movement of thel bar 47, due to the cooperation of wedging cams 49 with the washers 43 of screws 42, causes the supporting arm lugs 46 tightly to engage in the lateral notches 40 of the upturned ends 36 ofthe tray supporting straps 35.

In the embodiment of. the invention just described, the supporting arms 44 are restored to their raised or horizontal positions by separately moving them-as distinguishedY from the embodiment of the invention shown in Figs. 13 to 22 inclusive, wherein the restoration of the supporting arms to their horizontal positions is accomplished by actuation of the bar, which also adjusts their angularity with respect to the supporting surface of the tray. In the simplified construction of Figs. 11 and 1'2, the tray proper is indicated at 51 and the supporting straps, which preferably are welded to the tray bottom, are indicated at 52. Cushioning sleeves of rubber or the like are indicated at 53. Each of the straps 51 has an end 55 turned upwardly at right angles to the body of the strap. Hinged to each of the upturned strap ends 55, for swinging movement on a horizontal axis, is a tray supporting arm 56,-a slot in the upturned strap end and a loop formed on the contiguous end of the arm aiording the requisite hinge connection. When the tray of Figs. 11 and 12 is being carried, the arms 56 may be caused to overlie the supporting surface of the tray, as shown in the drawings, at which time said arms may be utilizedV to hold sandwiches, packages of cigarettes and other articles, in position on the tray. When the tray is to be applied to a car door, the arms 56 are swung to the dotted line position of Fig. 12,-

ready for insertion into a car door, as are the supporting arms of the tray previously described.V

In the preferred embodiment of our invention illustrated in Figs. 13 to 20'inclusive, the tray proper is illustrated at 57, the welded-on supporting straps are shown at 58, the upturned ends of the straps are shown at 59, and the cushioning sleeves with which the straps are provided areA indicated at 60. Each upturned strap end 59 is provided with a vertical rib 61, which preferably is pressed from the metal of the said upturned strap end, as indicated in Figs. 18 and 20.

'Pivoted to each of the upturned strap ends 59 is a tray supporting arm 62, the pivotal connection being afforded by a shoulder screw 63, the cylindrical unthreaded portion of which extends rather' loosely through an aperture 64 in the upturned strap end.

The operating bar for the supporting arms 62 is shown at 65, said bar lying between the supporting arm 62 and the upturned strap ends 59 and being provided with slots 66 which receive the cylindrical portions of screws 63,-said slots 66 having straight and curved portions, as shown in Figs. 14 and 15. Also Vformed in the bar 65 are slots 67, each of which is contiguous to one of the aforesaid slots 66. Each of the slots 67 comprises a relatively long straight portion merging, at shoulders 68 and 68a, into a shorter but parallel straight portion. Each of the tray supporting arms is provided witha pin 69, which is adapted to engage in one of the slots 67. The slots 66 and 67 and pin 69, at each end of the bar 65, are similarly but reversely arranged with respect to the corresponding slotsand pin at the other end of the bar, this being so because the tray supporting arms 62 are designed to swing simultaneously in opposite directions when actuated toward and away from their raised or horizontal positions.

Located at the lower edge ofT each end of the operating bar 65 are cams 70 and 70a, the cams being formed of the metal of the bar, and the cams of each pair tapering in opposite directions and being most narrow at their contiguous ends (see Fig. 19) Each pair of cams 70 and 70a is adapted to cooperate with one of the ribs 61 of one of the upturned strap ends 59.

The operating bar 65 preferably is provided at each of its ends with an offset finger piece 7l. Moreover, the operating bar preferably carries, at its central portion, a spring clip 72 adapted to receive and support a menu card or the like, indicated at 73. The said clip 72 is shown as consisting of a small piece of spring metal riveted to the bar 65, but if desired the clip may be welded to the bar or be in the form of a spring tongue struck from but not severed from the metal of the bar.

The lower ends of the tray supporting arms 62 preferably are provided with rubber tips 74 of the kind clearly illustrated in Figs. 17 and 21.

Let us assume that the tray supporting arms 62 are in the positions illustrated in Figs. 13 and 14 and that we desire to cause the said tray supporting arms to occupy the raised o-r horizontal positions indicated in Fig. 15. To accomplish this purpose the operating bar 65 is pressed to the left (Figs. 13 and 14). The first result of this movement of the bar 65 is an engagement of cams 70a with ribs 61 to insure that both of the pins 69 are in cooperative engagement with their respective slots 67. The next result of the said left hand movement of the operating bar 65 is the engagement of the shoulders 68 of the slots 67 with the pins 69. When the said shoulders engage the said pins, the supporting arms 62 simultaneously are swung toward each other and upwardly to the positions shown in Fig. 15,-the curvature of the slots 66 permitting the proper cooperation of the pins 69 with the slots 67 and permitting the pins 69 to engage in the shorter portions of the slots 67 after the suppo-rting .arms 62 have reached the horizontal positions of Fig. l5. With the upper supporting arms 62 in the raised or horizontal positions of Fig. 15, and with the operating bar 65 in the positions of Figs. 15 and 19, the cams 70a of the bar 65, cooperating with ribs 61, tighten up the moving parts and hold them against rattling.

When it is desired to mount the tray upon an automobile door or the like, the operating bar 65 is moved from left to right (Figs. 13 and 15). The rst result of this movement of the bar 65 is a movement of the cams 70a with respect to ribs 61 to permit a loosening of the relatively movable parts. The next result of such movement of the operating bar.65 is the engagement of shoulders 68a of the slots 67 with pins 69. When this occurs, the tray supporting arms 62 are forced downwardly and away from each other tothe positions shown in Figs. 13 and 14,-the curvatures of the slots 66 again permitting the proper cooperation of pins 69 with their slots 67. The supporting arms 62 now may be inserted into the glass panel opening of an automobile door in the manner shown and described in connection with that embodiment of our invention illustrated in Figs. 1 and 2. If, after the insertion of the tray supporting arms 62 into the car'do'or, it is vfound that the loaded tray inclines downwardly away from the door, the suppporting surface of the tray may be brought to the true horizontal by from the door, the supporting surface of the 65 (Figs. 13 and 14) until the cooperation of the cam 70 with the ribs 6l has accomplished the desired result.

Having thus illustrated and described our invention. in several practical embodiments, we do not limit ourselves to the particular construction and arrangement of parts herein described and illustrated, the tray being susceptible tomany modifications without departure from the scope of our invention, as defined by the appended claims.
